Subject: [PATCH 0/2] drm/bridge: it66121: Add it66122 support

Hi,

Add support for IT66122, which for all practical purposes is
drop in replacement for IT66121 except for the ID register
definition.

BeagleY-AI uses this new part as the old part is no longer in production
as far as I understand.

Now, BeaglePlay uses it66121 at the moment, but at some point, it might
end up flipping over to the new part.

An alternate implementation could be to drop the revision check or make
it66121 check include alternate ID check.. but that seems a little
non-standard.. Anyways, I suppose mediatek platforms will face this
problem as well at some point.
